> Note also that China is currently building 24 GenIII nuclear plants. Too slow. What is it? 30 GW production capacity? 40? 50? China is going in the direction of total 1300 GW production capacity with just coal. > Building a nuclear plant takes 10-15 years. A single one. I was taking about scale. To replace the coal power plants of China, one would need to build 1000 reactors.

> A single one. You think they are built in series? Like one after the other? Do you place that same requirement on renewable plants? > To replace the coal power plants of China, one would need to build 1000 reactors. The Chinese plants under construction will bring nuclear from 2% of the current grid to 20% by 2030. So, no, it's not 1000 reactors, it would be 100 - which is entirely doable. ...and indeed they are planning for an additional 1500GW of nuclear power construction AFTER this current set is finished.

See here for nuclear: https://en.wikipedia.org/wiki/Nuclear_power_in_China https://en.wikipedia.org/wiki/Nuclear_power_in_China --- As of March 2019, China has 46 nuclear reactors in operation with a capacity of 42.8 GW and 11 under construction with a capacity of 10.8 GW.[4][5] Additional reactors are planned for an additional 36 GW. China was planning to have 58 GW of capacity by 2020.[3] However, few plants have commenced construction since 2015, and it is now unlikely that this target will be met.--- Nuclear will be far from providing 20% in 2030.
